Abstract
Description
本発明は、口輪筋のトレーニングに用いられる口輪筋トレーニング器具に関する。 The present invention relates to a muzzle muscle training apparatus used for muzzle muscle training.
口唇周囲の筋肉である口輪筋は主に口を閉じる際に働く筋肉であり、発音、食塊形成、嚥下、表情を作るなど様々な働きに関与している。口輪筋の筋力低下は口唇閉鎖不全の誘因となり、口腔環境の悪化および口腔機能の低下、歯周疾患を引き起こすリスクを高める。 Muzzle muscles, which are muscles around the lips, are muscles that mainly work when closing the mouth, and are involved in various functions such as pronunciation, bolus formation, swallowing, and facial expression. Loss of muscle strength of the orbital muscles triggers lip insufficiency, increasing the risk of deteriorating oral environment and oral function and periodontal disease.
高齢者の場合、疾病や加齢による口輪筋の衰えにより口腔機能が低下すると、食塊を食道に送り込む動作が正常に行われず、誤嚥が発生しやすくなる。そのため、誤嚥に起因する肺炎の発症リスクが高まる。高齢者の死因において誤嚥性肺炎は上位を占めており、嚥下障害の改善を目的とした口輪筋のトレーニングが推奨されている。 In the case of an elderly person, when the oral function is lowered due to the deterioration of the orbital muscle due to illness or aging, the operation of feeding the bolus into the esophagus is not performed normally, and aspiration tends to occur. This increases the risk of developing pneumonia due to aspiration. Aspiration pneumonia is the leading cause of death among the elderly, and training of the orbital muscles for the purpose of improving dysphagia is recommended.
小児の場合、口唇周囲の筋力バランスが正常な場合、前歯の前突は外側から口唇により抑止されるが、口唇閉鎖不全に陥っていると前述の口唇による抑止効果が得られず、前歯の前突傾向が強まることが指摘されている。この現象は、常時上唇と下唇および歯列が離間した状態になり、舌の位置が正常な場合と比較して下方や前方に位置するように変化し、前歯に負荷を与える状態となっているために起こる現象である。口輪筋の筋力低下に誘発された口唇閉鎖不全が長期にわたると、鼻呼吸から口呼吸へ変化し、口腔内乾燥や唾液機能の低下からう蝕、歯周病のリスクが高まり、のどや扁桃周囲の乾燥からアレルギー疾患のリスクが高まる。近年小児期でも睡眠時無呼吸症候群を発症する小児が増加傾向にある。そのため様々な疾患の予防を目的として口輪筋のトレーニングが推奨されている。 In the case of children, when the muscle strength balance around the lips is normal, the frontal protrusion of the front teeth is suppressed by the lips from the outside, but if the lip closure failure occurs, the above-mentioned deterrent effect cannot be obtained and the front teeth It has been pointed out that the tendency to suddenly increase. This phenomenon is that the upper lip, lower lip, and dentition are always separated from each other, and the position of the tongue changes to be lower or forward compared to the normal case, causing a load on the front teeth. It is a phenomenon that occurs because of Long-term lip insufficiency induced by muscle weakness in the muzzle muscles changes from nasal breathing to mouth breathing, increasing the risk of caries and periodontal disease from dry mouth and decreased saliva function, throat and tonsil The risk of allergic diseases increases from the surrounding dryness. In recent years, the number of children who develop sleep apnea syndrome is increasing. Therefore, training of muzzle muscles is recommended for the purpose of preventing various diseases.
矯正分野では、歯列不正の原因が口輪筋の低下によるものも少なくないため、歯列矯正後の後戻り防止を目的とした口輪筋のトレーニングが採用されている。歯列の乱れには前述のとおり、口唇周辺の筋力の不均衡や舌の位置に起因するものがあり、矯正治療による歯列の回復のみではなく、口輪筋のトレーニングにより根本的な原因を取り除くことで再発防止を図っている。 In the orthodontic field, the cause of malalignment is often due to a decrease in the muzzle muscles, and therefore, training of the muzzle muscles for the purpose of preventing reversion after orthodontics is adopted. As mentioned above, dentition disturbances are caused by muscle strength imbalances around the lips and the position of the tongue. By removing it, we are trying to prevent recurrence.
口輪筋は多くの表情筋と繋がる筋肉であり、口輪筋に負荷を与えることで広い範囲の表情筋を鍛えることが可能である。表情筋のトレーニングは、ほうれい線の解消や肌のたるみや皺の予防など、顔貌の改善効果があるとも言われており、医療分野に留まらず、美容分野においても口輪筋のトレーニングの効果が注目されている。 The muzzle muscles are muscles connected to many facial muscles, and it is possible to train a wide range of facial muscles by applying a load to the muzzle muscles. Facial muscle training is said to have an effect of improving facial appearance, such as elimination of constriction lines and prevention of sagging skin and wrinkles. The effect of training of muzzle muscles not only in the medical field but also in the beauty field Is attracting attention.
これまでにも口輪筋の筋力回復および口唇閉鎖不全の改善を目的とした種々のトレーニング器具が開発されている。特許文献１には、口腔内装着部を牽引する方式の口輪筋鍛錬装置について記載されている。上記特許文献１に記載されているマウスピース部は柔軟性のある材質を採用することで様々な口内形状に適応可能としているが、材質が軟質であるため、牽引部から離れるほど牽引したときに変形が生じやすく、筋肉に与える負荷が小さくなる等の安定性に欠ける。また、前記マウスピース部を薄板形状としているため、牽引したときに前記マウスピース部の辺縁と粘膜面が線接触となり、最大限のトレーニング効果を得ることができない。上記特許文献１に記載の口輪筋鍛錬装置は口腔内装着部と牽引部のみで構成され、誤飲の発生リスクを排除できているとは言えない。 In the past, various training devices have been developed for the purpose of restoring muscle strength and improving lip closure failure. Patent Document 1 describes a muzzle muscle training device that pulls the intraoral mounting portion. The mouthpiece described in Patent Document 1 is adaptable to various mouth shapes by adopting a flexible material, but because the material is soft, when it is pulled away from the towing unit Deformation tends to occur and lacks stability, such as a smaller load on the muscle. In addition, since the mouthpiece portion has a thin plate shape, the edge of the mouthpiece portion and the mucosal surface are in line contact when pulled, and the maximum training effect cannot be obtained. The muzzle muscle training device described in Patent Document 1 is composed only of an intraoral mounting part and a traction part, and cannot be said to eliminate the risk of accidental ingestion.
特許文献２には口裂保持部を上唇と下唇で挟み、意識的に口裂を閉じることで口唇閉鎖矯正を行う器具について記載されている。上記特許文献２の口唇閉鎖矯正器具には赤唇縁当節部が具備されているが、誤飲を防止するのに十分な寸法とは言えず、誤飲の恐れを完全には排除できない。よって、高齢者や小児が自分自身でトレーニングを行うには誤飲の危険性があるため、トレーニング時には家族等の付き添いが必要となる。
特許文献３には各種樹脂材にて作製された器具を上唇および下唇に挟み、具備された引張紐を上下、左右および前方に引張操作をすることにより口輪筋を鍛錬するための口唇器具が記載されている。上記特許文献３の口唇器具は、形態上の制限から装着位置を変更することは困難であり、口輪筋以外の筋肉に主眼を置いたトレーニングへの対応は難しい。また、上記特許文献３に記載の口唇器具は具備された引張紐を２方向に引っ張るなどの操作を必要とする。
口輪筋を鍛えることにより、口輪筋と繋がる周囲の筋肉に対し、間接的に刺激を加えることは可能であるが、上記特許文献２や上記特許文献３に記載されるような器具では、口唇周囲の筋肉を直接的に刺激するトレーニングは行えない。
It is possible to indirectly stimulate the surrounding muscles connected to the muzzle muscles by forging the muzzle muscles, but with the instruments described in
また、口輪筋に関わらず筋力トレーニングは、継続して行うことで効果が得られるものである。その点において、上記特許文献２に記載の口唇閉鎖矯正器具は、意識的に口裂を閉じるトレーニング手法や誤飲に対する周囲の注意が必要など、トレーニング実施のために本人および周囲の行動が制限されるという問題がある。上記特許文献３に記載の口唇器具も引張紐を２方向に引っ張るなどの操作により、実施者の行動が制限されるという同様の問題があった。
In addition, the muscular strength training is effective regardless of the muzzle muscles. In that respect, the lip closure correction device described in
そこで、本発明における課題は、牽引時に変形しない硬質な材料によって安定した負荷環境を提供する口腔内装着部を具備し、前記口腔内装着部が歯面と口唇および頬粘膜の間の任意の位置に装着可能な形状を有することで、口輪筋のみではなく、口唇周囲の種々の筋肉にも直接的に刺激することが可能な汎用性の高い口輪筋トレーニング器具を提供することである。 Then, the subject in this invention comprises the intraoral mounting part which provides the stable load environment with the hard material which does not deform | transform at the time of towing, The said intraoral mounting part is arbitrary positions between a tooth surface, a lip, and a cheek mucosa. It is to provide a versatile muzzle muscle training apparatus that can directly stimulate not only the muzzle muscles but also various muscles around the lips.
また、牽引時に口腔内装着部が粘膜面と面接触することによって、より筋肉を引き伸ばすとともに、意図しない負荷の集中を回避し、トレーニング効果の向上が図れる口輪筋トレーニング器具を提供することである。 Another object of the present invention is to provide a muzzle muscle training device that stretches the muscles more and avoids unintentional load concentration and improves the training effect by bringing the intraoral mounting part into surface contact with the mucosal surface during towing. .
トレーニング対象となり得る、高齢者や小児でも誤飲の恐れがなく、実施者単独でも安全にトレーニングが実施できる簡便な装着方法および操作方法とし、トレーニングの継続に対して、実施者および周囲への負担を軽減できる口輪筋トレーニング器具を提供することである。 There is no fear of accidental ingestion even in elderly people and children who can be trained, and it is a simple wearing method and operation method that can be safely performed by the practitioner alone, and the burden on the practitioner and surroundings for continued training It is to provide a muzzle muscle training apparatus that can alleviate the problem.
